Dear Editor, Considering that today there is a growing concern with the quality of cells, tissues, and organs destined for the treatment of human diseases, within this context, many studies have been conducted by public institutions. Several organizations store biological samples and data, given the difficulty to obtain and characterize many of these materials, as they can possibly be used in new projects. Based on the current legislation, storage, as mentioned, characterizes a biobank.() These structures require investment for maintenance […]

Dear Editor, The article “Effects of overnight fasting on handgrip strength in inpatients” is relevant and has practical application in the hospital environment. Nevertheless, a few methodological issues need to be clarified: […]

Concerning the article by Maia et al., we have the following comments. Since noncompaction also known as left ventricular hypertrabeculation (LVHT) is frequently associated with genetic disease, first-degree family members should be screened for LVHT, visual impairment, and nystagmus. Disability and visual impairment should be specified and results of cerebral magnetic resonance imaging presented. Left ventricular hypertrabeculation is not congenital in each case. Acquired LVHT has been reported, particularly in patients with neuromuscular disorders (NMDs), professional athletes, and pregnant women. […]

Initially, we are grateful for the considerations made by Rodrigues et al. The central idea of the study was to investigate if overnight fasting, often required for surgical or diagnostic procedures, has an impact on muscle function. Doubtless, the findings showed that the 8-hour night fasting, although physiological, resulted in decreased functional capacity determined by dynamometry. This is aggravated by the fact that fasting for procedures in Brazilian hospitals, prescribed for 8 hours, is really longer, and is estimated at […]

Thank you for interest in our paper. The manuscript was written to discuss the question about sports eligibility in Paralympic athletes. Our case did not show familiar antecedents of cardiac disease. During the study, we could not have access to patient’s family history to verify her family incidence of cardiopathy. […]

Letter to the editor, The healthcare work process is complex and engages several health professionals, who along with other professionals develop multiple activities essential to support the organizational structure. Thus, continuous interaction among players is required to carry out patient care. Any teamwork is challenging, for there is a diversity of individuals and ideas in face of a work process shared by all. […]

Dear Editor, Although published in 2003, the article “Linear programming applied to healthcare problems”() is very up-to-date and important for the first contact with linear programming, particularly in the field of health. Congratulations to the author for this initiative. I analyzed this work to use it in a undergraduate degree in Mathematics. However, I observed the solutions obtained for the two problems described present inconsistencies that may lead readers with little experience to make mistakes. For the diet problem, the […]

Dear editor, Francis Bacon proposed in 1620 that scientific knowledge should be not only based on intuitive hypothesis, which is eventually limited to establish a premise before an experience, and, therefore, restrict thinking in a way that correlate with this principle. Currently, Big Data has promoted shifts on previous paradigms. New studies are based on network through massive amount of data and even less based only on intuitions.() Big Data applied to people management is called “People Analytics” and it […]

Dear editor, In medieval times knowledge was limited to monastic libraries and access was not granted to the society. In 18th century, scientists used to travel to different countries to communicate their science in public lectures. In the same century, science become an institutionalized and professionalized activity, but it was restricted to limited communities.() Today, although information is easily transmitted, knowledge generation still limited to universities and large laboratories that use specific communicate channels to diffuse their science. In the […]
